Does any one know if there is a way to dump only a chunk of memory to disk using VS? Basically, I want to give it an address and a length, and have it write the memory to disk. That way I can do a binary diff. Thanks. ...
I have a simple C++ with Boost like this: #include <boost/algorithm/string.hpp> int main() { std::string latlonStr = "hello,ergr()()rg(rg)"; boost::find_format_all(latlonStr,boost::token_finder(boost::is_any_of("(,)")),boost::const_formatter(" ")); This works fine; it replaces every occurrence of ( ) , with a " " However, I get ...
Writing a templated function, I declared: template <typename T> T invertible(T const& container, T::size_type startIndex, T::size_type endIndex); Compiling with g++ 4.0.1 I got the error: error: 'T::size_type' is not a type ...
I have an C++/CLI assembly consisting of approximately 50 source files. The code in this assembly links statically to a number of C++ libraries to do various 'heavy-lifiting' type tasks. I am using Visual Studio 8 (2005) SP1 to build this assembly. Building just this assembly (without dependencies, etc) via 'Project Only'->'Rebuild On...
So, I have an abstract class Panel and an implementation of it MyPanel. They look similar to this: class Panel : public QWidget { public: Panel(QWidget* parent = 0) = 0; virtual ~Panel() = 0; // but wait, there's more!! }; class MyPanel : public Panel { public: MyPanel(QWidget* parent = 0); ~MyPanel() {}; // nothing to do her...
Guys, I have the following code that is inside a big while loop that iterates over a tree. This is as fast as I can get this routine but I have to use a goto. I am not fundamentally against goto but if I can avoid them I would like to. (I am not trying to start a flame war, please.) The constraints: The current=current->child() is ex...
I know PC-Lint can tell you about headers which are included but not used. Are there any other tools that can do this, preferably on linux? We have a large codebase that through the last 15 years has seen plenty of functionality move around, but rarely do the leftover #include directives get removed when functionality moves from one im...
Hi, In order to make a binary comparer I'm trying to read in the binary contents of two files using the CreateFileW function. However, that causes the whole file to be bufferred into memory, and that becomes a problem for large (500MB) files. I've looked around for other functions that'll let me just buffer part of the file instead,...
I have been writing an OpenGL game engine for a while which uses SDL for all the window management and for portability. I would like to create a level editor using the full engine. The engine itself isn't at all tied in with SDL except for input. I would like to use wxWidgets for the GUI and I have been looking at some OpenGL samples whi...
I am trying to setup a repository of reusable code. I was thinking about having each reusable code module have a certain “Maturity Level” rating. The rating would be defined as the level at which a reusable code lies within a certain set of requirements. The highest maturity level will be the highest degree of standard across a predef...
I am writing a Visual Studio add in and need to marshall a managed CodeElements object to it's unmananged form. I just need the pointer in memory, as I can cast it and treat it like a CodeElement on the unmanaged side. [DllImport("CodeMethodsToString.dll")] private static extern BSTR* CodeMethodsToString(void* functionObject); p...
As a follow up to my original question about a small piece of this code I decided to ask a follow up to see if you can do better then what we came up with so far. The code below iterates over a binary tree (left/right = child/next ). I do believe there is room for one less conditional in here (the down boolean). The fastest answer wins!...
Hi, I am using OpenMP to do multithreading with my nested loops. Since new to this stuff, I am not sure if I am using OpenMP in the correct way so that it can actually do the parallel programming. So I like to know if I can measure the performance of my C++ program that uses OpenMP so I can tell it actually works and I am on the right tr...
I'm building a system, with C++, that uses Tokyo Cabinet (original API in C). The problem is I want to store a class such as: class Entity { public: string entityName; short type; vector<another_struct> x; vector<another_struct> y vector<string> z; }; The problem is that vectors an...
I'm in Visual Studio 2003. I have a function in a very common module which requires 3 other modules. I want only projects using the new function to have to include the 3 other modules, and those that don't reference the function to link without "unresolved external symbol" errors. I tried function level linking, OPT:REF and every proj...
We've been given a C++ code base that was apparently developed using Rational Apex as the front end. In our opinion, Apex is less than ideal for C++ development. We're looking for an IDE we can use that has syntax highlighting, code-walking (go to definition, show usages), and isn't a pain to use. We've looked at NetBeans, Sun Studio a...
Both QWebFrame and QWebPage have void loadFinished(bool ok) signal which can be used to detect when a web page is completely loaded. The problem is when a web page has some content loaded asynchronously (ajax). How to know when the page is completely loaded in this case? ...
How can I read from an std::istream using operator>>? I tried the following: void foo(const std::istream& in) { std::string tmp; while(in >> tmp) { std::cout << tmp; } } But it gives an error: error: no match for 'operator>>' in 'in >> tmp' ...
I'm wanting to become conversant in the use of the Standard Template Library. If I come across a general reference or beginner's guide published around 1995-97, can I rely on the information in it? How much has STL changed in the last dozen years? ...
I have been told that a handle is sort of a pointer, but not, and that it allows you to keep a reference to an object, rather than the object itself. Some further clarification would be lovely though, thank you! ...
